In this paper a simulation approach for defaultable yield curve is developed within the Heath et al. (1992) framework. The default event is modelled using the Cox process when the stochastic intensity repre sents the credit spread. The forward credit spread volatility function is affected by the...

Maximal Oxygen Consumption (VO2 max) is one of the most important predictors in cardio respiratory domain. The present work deals with the relationship between the six minute walk test to the maximal oxygen consumption. Pneumatologists and cardiologists are very interested in this relationship...

In this paper, a concept of approximate social Nash equilibria is considered and an existence result is given when the strategic spaces of the players are not compact. These have been obtained using an approximate fixed point theorem. As an application of the existence of such approximate social...
